The lamp position monitoring relay 4 is a low-level 5V relay and is provided with a normally-open contact and a normally-closed contact (COM is a common end, NO is a normally-open end and NC is a normally-closed end), the volume is 43mm 17mm 18.5mm, the working voltage is 5VDC, the trigger voltage is 0-3.5VDC, and the contact capacity is 250VAC10A or 30VDC 10A. VCC is connected with the positive electrode of a 5V power supply, GND is connected with the negative electrode of the 5V power supply, and the signal trigger end (low level trigger is effective) of the IN relay.

The DO output end of the photoresistor module 7 is connected with the IN end of the lamp position monitoring relay 4, when the lamp position is turned off manually, the photoresistor module 7 cannot sense the brightness of light, and when the brightness of the light cannot reach the set threshold value IN the module, DO outputs high level, and the lamp position monitoring relay 4 does not act; when the manual lamp position is lighted, as the light brightness is sensed by the photoresistor module 7, when the light brightness reaches the set threshold value in the module, DO outputs low level, and the lamp position monitoring relay 4 acts, so that the function that whether an operator turns on the gas-off control panel to the manual position or cancels the manual position is realized.

The GPS-23 normally open type magnetic control reed switch is matched with the ferrite magnet 11, the magnetic control reed switch is used as a passive electronic switch element with contacts, the structure is simple, when magnetic substances are close to the glass tube, under the action of magnetic force lines of a magnetic field, two reeds in the tube are magnetized to attract each other, and the reeds can be contacted together, so that a circuit connected with the contacts is connected. When the external magnetic force is eliminated, the two reeds are separated due to the elasticity of the reeds, and the circuit connected with the contact points is disconnected. In practical application, the normally open magnetic control reed pipe 8 is arranged on the door frame, the ferrite magnet 11 is arranged at the same position of the door leaf corresponding to the door frame, when the door is opened, the ferrite magnet 11 is separated from the reed pipe 8, and a circuit connected with the contact is disconnected; when the door is closed, the ferrite magnet 11 is contacted with the normally open magnetic control reed pipe 8, and a circuit connected with the contact is connected.
